Appli-*canon meu February 13, 1923. serial No. i613,767.v

To all whom t mag] concern:

`Be it `known that I, DANIEL R. SoHoLns, citizen of they United States, resid-ing at hieago, in `the county of Cook and vState of 5 Illinois, have invented a certain new and useful improvement in Vindmills', of 4which the following is a full, clear, concise, and exact description.

My invention relates to windmills and has '1 for its object the provision of vimproved means for lubricating the wind wheel shafts. In my co-pending application Serial No. 573,591, filed July 8, 1922, I vhave disclosed a windmill employing lubricating mechal-3 nism including a basin containing lubricant and formed with a sleeve extension having an open outer end, a shaft jorirnaled in said extension, motion transmitting; mechanism including a gear wheel upon the shaft and 2U within the basin and dipping into the lubricant contained in the basin, and means for transferring lubricant elevated by the gear wheel to the shaft within the sleeve,r there being aV return passagebe-neath the sleeve 5 extension and connecting' the outer end thereof with the basin.4 `The aforesaid `basin is mounted to turn upon an uprightaxis and the sleeve extension of the basin is hori- `frontal.

` By means of my present invent-ion the lubricant conveying structure of the mill is Ill) much simplified, the invention being fullyl veiq'ilained in connection with the accompanying drawings inwhich Fig. v1 is a secf tional plan View illustrating portions of the windmill structure as' such is preferably Y made; Fig. 2 is a'sectional view on line 2 2 of Fig. 1; Fig. 3 is aside view of the upper portion of the windmill containing the mechanism of the invention; Fig. 4 is aseotional View `on line 4 4 of Fig. 1; Fig. 5 is a sectional view on line 5 5 of Fig'. 1; Fig. 6 is a sectional View on line (3 6 of Fig'. 1; g and Fig. 7 is a sectional view on line 7 7 l" of Fig. 3. Y

vLilie parts are indicated by similar characters of reference throughout the different figures. l

The wind wheel shaft 1 is provided with "o bearings 2, 2 and 3 carried by a gear housing 4l which is made imperforate, particu larly at its lower portion, so as to contain lubricating oil illustratedat 5 in its lower portion. The shaft 1 carries pinions or small spur gear wheels 6 which are in driving mesh engagement with larger gear `wheels 7 4that are operatively connected with a suitable load operating pitman which-does not need to be illustrated.` A washer 8 is pressed against the left lface of the left :'pinion 6 by a coni-cal coil spring 9` which tends to distend axially of the sha-'ft 1 .to effect" the application of its pressure against' the washvere, the base of the spring 9 resting against the housing t at the right end of the bearing 2. The washer 8 is circular at its right and left hand sides but is enlarged-'at itsupp'er ydireetingtheoil into an openingV 14C in the bear1ng2. The oil conveyed through the Vtrou-gh l-2is 'directed to the opening 14 by the leader `13 and'finds its way directly to 80 the sli-'aft r1 at thejopening 14; and works endwise of the shaft `in jboth directions.

A spiral groove 22 promotes the passage of the lubricant through the bearing 2. It is desirable to limit aportion of the left hand pinion 6to` engagement with the right hand border of the trough 12 as much as possible, on which account the washer 8 has adownwardly extending' projection `1G which bears against the associate pinion 6 outside of the circle of the sides of the washer.

The basin is mounted to turn upon an upright axis in any usual or sui-table way and is vformed with a horizontal sleeve eX- tension 17Y in ,whichthe wind wheel shaft 1 95 is journaled` and through which the shaft extends at bothV ends. The bearings 2 and 2 are spaced apart between the ends of the sleeve extension to form an annular lubricant receiving passage 18 from which 10o a portion of the lubricant returns directly to the basin as will appear, the balance of the lubricant working its way to the left through the bore of the bearing 2 and thence throughthe outer open end of this 105 bearing and sleeve extension to find its way back to the basin through the return passage 19 which underlies and is also disposed laterally of the slee-ve extension 17, this passage being preferably formed in an enlarge- 4110 ment of the sleeve extension and communicating with the outer open end thereof. The i spaces 18 and 19 are thrown into communication by the opening formed through a side of the sleeve extension 17 of the basin to bring the space 18 into communication with the return passage 19. The opening 20 is in a side portion of the sleeve eX- tension 17 of the basin in order that oil may accumulate in the spaceV 18 to a depth sufficient to reach the shaftl. By shaping the passage 19 so that a portion of it will lie laterally of said opening 20, a special passage to bring this opening into communication with the basin is not required.

The shaft 1V projects at its left hand end through and beyond the sleeve extension 17 and carries the wind wheel 22. To'guard the open end of the sleeve'eXtension from the weather to prevent water from finding its way to the lubricant containing basin, the hub 21 is formed with a portion 23 wh'icli surrounds the out-er end of the sleeve eX- tension and projects inwardly beyond the same toward `the basin, the sleeve extension terminating short of the closed outer end` ofthe hub portion 23. When the wind Ywheelis in the wind, driving rain is prevented -from being wind driven into the sleeve, extension and the lubricant returning passages communicating therewith.. If the 'wind wheel is out of the wind thesides of the hub Aextension 23 will similarly guard the lubricant. The oil ducts that communicate'withthe bore of thek sleeve extension are preferably so disposed 'and the lubricant level in' the basin is desirably such that the lubricant will not rise-above the axis of the wind wheel shaft. j i Thile I have hereinshown and particuY larly described the preferred embodiment 'of my invention I do not Wish to be limited axis and formed with a horizontal sleeve extension having an open outer end; a shaft in said extension, there being space between said shaft and extension and between the ends of the extension for receiving lubricant; powery transn'iittingv mechanism including a gear wheel upon the shaft and within the basin and dripping into `the lubricant contained in the basin; means for transmitting lubricant elevated by the gearV wheel to the inner end portion of the aforesaid sleeve extension, there being a return passage beneath the sleeve" extensionand connecting the outer end thereof with the basin, and also an opening in a side of the 'sleeve extension at the aforesaid space to the weather,y said sleevek extension terminatingshort ofthe closed end of said hub portion.

2.- In a windmill, the combination with a basis mounted to turn upon an upright aXis and formed with Va' horizontal sleeve extension having an open outer end; a shaft in said extension, there being space between said shaft. and `extension and between the ends of the extensionV for receiving lubricant; power transmitting mechanism including a gear wheel upon the shaft and within the basin and dipping into the lubricant contained in the basin; means for transmit ting lubricant elevated by the gear wheel to lthe inner end portion of the'aforesaid ysleeve extension, there being a return passage beneath the sleeve extension and connecting the outer end thereof with the basin,

and also an opening in a side of the sleeve extension at the aforesaid space to bring this space into communication with said return passage; and a Wind wheel upon the outer end of the shaft which projects beyond said sleeve extension..

-In witness whereof, I hereunto subscribe my name this 29th day of January,.A. D.
